Hi! I have a Note 4, not rooted, stock rom. I use a USB drive and an OTG adapter to hold roms for emulators, but in the FPSE, it only shows the SD card under external storage. Under internal storage, the USB drive doesn't show there either- it is mounted in /storage/usbdriveA or something similar, and the /storage directory doesn't show up at all. It shows in other apps and work in other emulators. In FPSE, I can't find a way to select between external storage devices - it seems to default to the SD card only. Anybody have any ideas on how to use a USB drive with FPSE? Thanks!
